 Old Astronomy: Royal Greenwich Observatory and Stonehenge.

with Bill Spizzirri

One of the advantages of traveling as an amateur astronomer is that you see and understand astronomy related tourist attractions in a depth and from a perspective that others may not. Bill will share with us his travels to and experiences of Stonehenge and the Royal Greewicht Observatory,  two of Englands premiere astronomy sites, with his signature wit and insight.

Speaker Bio: Bill Spizzirri has been an amateur astronomer for 50 years is a member of HAS and has also been a member of an astronomy club near Chicago for 36 years and counting. He served there as President for two years and has held other offices. Bill is now a retired software analyst and grandpa of three. His main astronomy activity these days is teaching children about our universe.

Cataclysmic Variables -- Stars that go Boom

with Walt Cooney

Dr Justin Filiberto.jpg

Cataclysmic Variables are a broad class of variables that undergo violent nuclear outbursts.  These events can quickly drive their brightness up many magnitudes.  They include the familiar novae and supernovae, but also include other varietals like dwarf novae, recurrent novae, nova-like variables, polars, intermediate polars and all kinds of variable stars that light off with little or no warning.  

Most cataclysmic variables are binary star systems where a white dwarf siphons mass from the companion.   In the presentation, we’ll discuss how these binary systems that start off as a pair of normal main sequence stars eventually go so horribly awry.  We’ll also talk about the work amateur astronomers have done for the AAVSO and for pro-am collaborations like the Center for Backyard Astrophysics that have led to significant advances in the understanding of cataclysmic variables.

Speaker Bio – Walt Cooney is a retired chemical engineer who has been an avid amateur astronomer since 4th grade when he did a report on the constellation Orion.  He was raised in Titusville, Florida where his dad was an engineer for NASA.  He has a B.S.Ch.E from the University of Florida and an M.S. in chemical engineering from Cornell.   He is the author or coauthor of 45 papers in astronomical journals, and discoverer of 64 asteroids and 59 variable stars including 3 in Columbus.   Asteroid (35365) Cooney was kindly named after Walt by Dr. Petr Pravec of the Ondrejov Observatory in the Czech Republic.

October 10, 2020, 6:30PM: Novice Lab at the Dark Site

Join us at the Dark Site for a hands-on course for learning to navigate the night sky. Make sure as always to bring your red flashlights and insect repellent, but also be sure to bring a folding chair to sit in, and some paper and pen/pencil. Schedule of activities is as follows:

7:15-8:15 - detailed presentation on general sky mechanics plus a tour of the constellations.
8:15-8:45 - constellation sketching - we will all begin working on the AL's Constellation Hunter program together
8:45-11:30 - everyone will get the opportunity to locate various objects manually using my 10" dob.
The program concludes in time for anyone who wishes to leave at the 12 am light window. But of course, anyone is welcome to stay longer and observe.

Please RSVP to [email protected] (link sends e-mail) so that we know how many people will be there for the class.  Clear skies!
